HPE6432_SetQGainDac

ViStatus HPE6432_SetQGainDac (ViSession instrumentHandle,

ViUInt16 qGainDac);

Purpose

This function sets a value for the Q Gain DAC.

Q Gain is used to enter compensation values for internal gain

impairments for the Q signal path. Since it is the ratio of I Gain to

Q Gain that is important, it is usually only necessary to make

adjustments to I Gain or Q Gain, but not both.

Factory Preset Value: 2048 (Recommended)
